Evaulation of the reliability of computer and artificial intelligence based cephalometric drawing programs in orthognati̇c surgical treatment

Aim: The aim of this study is to evaluate the reliability of the WebCeph program, which is an artificial intelligence-based cephalometric drawing program, before and after operation in patients undergoing orthognathic surgery, by using Dolphın Imaging program, which is an computer-based cephalometric drawing program. Individuals and Methods: Fifty patients (23 males, 27 females) with a mean age of 22,760±3,041 who underwent orthognathic surgery were included in the study. Lateral cephalometric radiographs taken 1 month before and 1 month after orthognathic surgery operation of 50 patients included in the study were evaluated using the artificial intelligence-based cephalometric drawing program WebCeph and the computer-based cephalometric drawing program Dolphin Imaging. In order to evaluate the methods in the study, a total of 29 parameters, 15 of which are angular and 14 of which are linear, were selected. Result: Methods before orthognatjic surgery include Aricular Angle (°), Gonial Angle (°), Björk Sum (°), Y Axis Angle (°), U1-SN (°), U1-NA (°), L1-NB (°), IMPA (°), Nasolabial Angle (°), A-Nperp(FH) (mm) (°), Pog-Nperp(FH) (mm), Upper Lip- E Plane Distace (mm) parameters statistically significant between methods difference detected. Methods after orthognathic surgery include Articuler Angle (°), Gonial Angle (°), Björk Sum (°), FMA (°), Y Axis Angle (°), Facial Depth (°), U1-SN Angle (°), U1-NA Angle (°), L1-NB Angle (°), IMPA (°), Nasolabial Angle (°), Facial Convexisy (mm), A-Nperp (FH) (mm), Pog-Nperp (FH) (mm), U1-NA Distane (mm), Upper Lip-E Plane Distance (mm) parameters were statistically significantly different between the methods. Conclusion: Although artificial intelligence-based cephalometric drawing programs have been developed to standardize the researcher-induced measurement difference, the intervention of the researcher is needed in order to be used in routine orthodontic practice.
